21 Amazing Examples of How Blockchain Technology Is Revolutionizing Everyday Life
The early development of blockchain technology BCT has already demonstrated the technology's potential to serve the needs of different industries. BCT has also become established as a popular research topic in different scientific disciplines.
This paper aims at introducing how several relevant scientific disciplines—supply chain management; management, economics and finance; computer science; security engineering—see the research and education perspectives for BCT. A field review is conducted to present challenges and opportunities of BCT, as well as suggestions for future research and education on the topic as seen from the selected different perspectives.
The paper also presents methods for combining relevant disciplines in a modular online course to address the stated challenges and promote interdisciplinary blockchain education. Blockchain technology BCT is establishing itself as a research subject in various scientific disciplines.
As the technology combines traits from the fields of distributed systems, cryptography, peer-to-peer networking and other technologies, and carries promise of changing how managerial and legal processes are conducted, research focused on blockchain often exceeds the boundaries of a single discipline Zhang and Lee, Furthermore, the interdisciplinary scope of the research on BCT is prompted by a range of industries for which BCT use cases and proofs of concepts can be found today.
In this paper, we present four scientific disciplines and methods for interdisciplinary education aimed at building a knowledge base, which is at the same time domain-specific and interdisciplinary.
Such knowledge is much sought by experts concerned with the development and integration of enterprise blockchain solutions Forbes, Over all industries and application areas, the use of BCT can have an influence on the product-, information-, and financial flows of enterprises Jakob et al. A typical supply chain as illustrated in Figure 1 is used as a bases to set the interdisciplinary scope for the field review in this paper. In enterprises, many blockchain use cases are seen throughout the whole supply chain and reach from data sharing to certification bottom of Figure 1.
Out of ten direct and indirect value-adding functions middle and right side of the grayed area in Figure 1 , we selected and highlighted three functions and their associated scientific disciplines for our field review. The selected functions have a great relevance in context of the development, integration, and use of enterprise blockchain solutions 1 as explained on the left side of the grayed area in Figure 1. Figure 1. Enterprise functions involved in a blockchain-based supply chain.
Own Graphic. Inspired by Lambert et al. In the following, for the selected scientific disciplines, we will present current challenges and respective potentials of BCT, as well as relevant future research topics that we see necessary in this field. Today's supply chain networks consist of a large and yet increasing number of partners, who conclude various types of service agreements between one another.
The companies' supply chain management SCM coordinates the processes between manufacturers, dealers, suppliers, as well as logistics- and financial service-providers and therefore demands solutions for efficient and secure ways of data exchange. While in the past, SCM was mainly driven by its goal to minimize process costs, the current developments lead to a stronger focus on improving flexibility and resilience Seeck, To reach these novel targets in a supply chain, it is necessary to enhance trust and transparency in the cooperation between supply chain partners, even if they are competitors Henke, ; Christopher, This becomes challenging, as organizations increasingly operate on a global level, far beyond their national borders and legislation.
This often leads to concerns in terms of trust, especially when it comes to new partnership agreements. In addition, transparency issues materialize because partners don't have a clear consensus about who accesses which data, when, and for what purpose Kshetri, Another challenge occurs in procurement processes that are still characterized by a lot of manual operations and thus prone to error.
This leads to slow financial flows that are dissociated from the actual process of service provision. The synchronization of material-, information- and financial flow represents another important challenge in current supply chains Jakob et al. Not only by digitalizing but by substituting paper-based invoices through independently auditable smart contracts, BCT gives an opportunity to automate transactions and hence to better integrate physical and financial flows in the supply chain.
The missing trust between parties is substituted with trust in the technology and its cryptographic mechanisms. Blockchain solutions bring along the possibility for distributed consensus building, irreversible data storage, and automation of process operations and organizational principles.
Moreover, a decentralization of the entire transaction management can be achieved Jakob et al. Other than that, the evaluation of different blockchain frameworks' performances and concrete differentiations to already established technologies are topics relevant for further research. Additionally, research has to be conducted on the concrete business value of respective blockchain solutions and on the setup of involved parties within a blockchain network and their underlying business models Cole et al.
Also, incentive systems have to be considered to establish reasonable networks between different partner profiles. The interdisciplinary scientific field of management science MS concentrates its research on problem solving and decision-making in organizations.
Since its inception in the s, MS has broadened its scope from what was a narrow focus on applied mathematics to calculate profits, risks, and costs to include all organizational activities whose problems can be identified and structured Hopp, In the context of today's focus on Industry 4.
MS inquiry into blockchain is concerned with many technology-related questions, such as technology selection, innovation, user interaction, implementation, governance, compliance, and risks, among others Janaviciene and Fomin, BCT can deliver practical management, risk mitigation, and financial solutions to organizations Petrov, , as well as to change the nature of how economic agents transact Lumineau et al.
To date, however, outside of the financial services sector and specifically the world of cryptocurrencies, blockchain has had little to no discernible impact on business practices FT. The high failure rate of blockchain projects Forbes, signals that scholars and practitioners alike lack systematic and reliable information on actual opportunities and risks brought about by the new technology.
Management scholars and practitioners must further their knowledge on theoretical and practical limits to transaction costs, governance mechanisms, and risk mitigation to better understand the large range of possible ways to realize a blockchain system, and how those can meet the specific company business needs.
Organizational efficiency of blockchain-enabled automation will be the focus of OM and TM for years to come. What kind of decisions or contracts can or cannot be automated? Governance and dispute resolution of blockchain-enabled transactions will also remain the focus of management research Lumineau et al.
Financial methods for estimating transaction cost and return on investment may need to be adapted to take into account a different technological and organizational logic of BCT as compared to traditional IT systems.
Computer science is defined as the study of computation and information University of York, , dealing with computational problems, algorithms, and the design of computer systems hardware, software, and applications. Blockchain, as an academic topic, intersects with various subdisciplines in theoretical and practical computer science. Despite the increasing advancements in the computer science discipline, the success of blockchains full maturity and potential still faces some critical challenges.
First, at the core of a computer system, computing performance and reliability are closely related to the usability and efficiency of applications. Efficient computing is a significant concern, and it is non-trivial to enhance the scalability and ensure the data fidelity. Highly trusted software technology is the second challenge for computer science. As a leading role in dependable information systems, the reliability, safety, security, and survivability of software should be all ensured.
The third challenge lies in how to establish reliable new-generation peer-to-peer systems providing consistency guarantees. Current real-world computer applications mostly work in a centralized model, and users need to put their trust in a trusted third party Zheng et al. Fourth, the software lifecycle management, provenance, and platform interoperability under tight security requirements Marchesi et al. As an emerging interdisciplinary technology, blockchain exhibits great promise in overcoming these challenges from the computer science perspective.
Additionally, the self-enforcing smart contract enables automatic and reliable execution of the predefined functionalities. Concerning the last challenge, blockchain itself is a decentralized peer-to-peer system.
The study of efficient and practical consensus algorithms involves multiple disciplines, that is, mathematics, cryptography, computer science, and economics. Security engineering describes how to lower risks of intentional unauthorized harm to valuable assets to a level that is acceptable to the system's stakeholders by preventing and reacting to malicious harm, misuse, threats, and security risks Firesmith, On one hand, in the centralized systems, security risks such as data tampering attacks, denial of service, man in the middle and others are mitigated by introducing risk reduction decisions Mayer, ; Dubois et al.
The blockchain-based applications change the nature of the security risk mitigation. By removal of the centralized authority, one needs to deal with the risk-avoidance decisions Mayer, ; Dubois et al. By installing the blockchain-based application, one avoids the previous risks, because the centralized architecture is changed to the blockchain-based decentralized architecture. Depending on the type e. Introduction of the blockchain-based architecture, also introduces new security risks.
These risks should be mitigated by the newly designed BCT means, such as, pluggable consensus mechanisms, permissioned and trusted authority nodes, block verification protocols, and others.
Future research in the security engineering field must address the challenges associated with the new security risks. The research must transcend various traditional roles and knowledge domains. Engineers should contribute to the knowledge base related to the problem domain and application area.
Security engineers should be involved in designing the blockchain-based applications. This should be a collaborative activity since the newly designed systems should be agreed upon and understood by the project stakeholders. Finally, security engineers should help with the identification of the protected assets which potentially should be captured from the problem domain , their support by the system assets defined in the blockchain-based application , and the security risks.
Security engineering also includes the trade-off analysis while estimating the value of the protected assets, the severity of the security risks, and the cost of the security countermeasures. This is a challenging process and requires further research.
Integrating emerging technologies with far-reaching effects like BCT leads to complex challenges for all types of organizations and can only be mastered by collaboration, integrating different disciplines, and establishing interdisciplinary teams Laufs and Sandner, To foster innovation and effective interdisciplinary team work, interdisciplinary competence is becoming increasingly important Schier and Schwinger, ; Kachalov et al.
The process of defining interdisciplinarity has been ongoing for a longer period. Latucca et al. The focus here is on the integration and synthesis of different perspectives and methods for solving complex problems. The interdisciplinary setting brings with it opportunities such as rapid decision-making, cognitive diversity, and increased innovative content or creativity, as well as risks such as a lack of openness toward other disciplines, communication barriers, and conflict potential Nancarrow et al.
Especially in blockchain integration projects, the relationships between internal and cross-company actors often lead to the stated challenges. In this case, actors have difficulties in reaching a common understanding of objectives, capabilities, and requirements of the blockchain integration and lack a common technical language and regular basis Laufs and Sandner, Kachalov et al.
The understanding of interdisciplinary communication and demonstration of psychological readiness to apply the knowledge of relevant related disciplines are key elements Kachalov et al. Lattuca et al. The increasing market demand for interdisciplinary competences necessitates universities to support students' abilities to collaborate across disciplines, hence facilitating an interdisciplinary learning approach Brassler and Dettmers, In this way, students are sensitized to think beyond the limits of isolated disciplines and respective disciplinary cultures.
Also, the ability to deal with uncertainty in science and the appreciation of different perspectives in the solution process are enhanced by interdisciplinary learning. Interpretation tools are used to combine and integrate the most diverse knowledge structures, which can be further developed step by step with particular emphasis on metacognitive abilities and critical thinking Ivanitskaya et al.
Interdisciplinary learning can be stimulated by communicating and perceiving one's own and other disciplines, methods, or objects. As a reflection of BCT development trajectories, some professional profiles are changing. To summarize, development of interdisciplinary courses that offer students from different disciplines with comprehensive blockchain-related competences and knowledge helps understand the scope of BCT application and impact on different business environments and becomes a current and critical direction for university and professional education.
The aim of the project is to prepare students for their future interdisciplinary work assignments on the one hand, and to teach on the versatile application possibilities of BCT on the other hand. For the development of the course curricula, the analysis of current and future skill requirements for the further definition of learning goals is essential.
Blockchain
Previously, she was…. He believes blockchain is likely to have a lot more staying power than popular cryptocurrencies like Bitcoin, which he calls a flash in the pan. Blockchain is the underlying technology that many cryptocurrencies — like Bitcoin and Ethereum — operate on, but its unique way of securely recording and transferring information has broader applications outside of cryptocurrency. A blockchain is a type of distributed ledger.
Blockchain Technology for Government
The technology provides transparency as all users on the network have access to all records. Even if you aren't remotely interested in the financial world, you cannot escape hearing about cryptocurrencies such as Bitcoin, Ethereum, and Dogecoin, among several others. While cryptocurrencies have been all the rage these past few years, it is, in fact, blockchain technology that is allowing them to thrive. Invented by a person — or a group of persons — identified as Satoshi Nakamoto in , blockchain was largely responsible for the success of Bitcoin, arguably the most popular cryptocurrency today. Blockchain is a decentralised ledger of all transactions that are made across a peer-to-peer network. Blockchain eradicates the need for a central authority to oversee the transaction. This, as a result, grants autonomy to users over their assets and transactions. To understand blockchain better, one can compare it to a database. A database is just a collection of information relevant to a larger task at hand. For instance, a database of hospitals would contain data on patient specifics, staff, medicine, inflow and outflow of patients and medicines, among other things.
Blockchain Technology and How It Is Used in Cryptocurrencies: All You Need to Know
When bitcoin first came on the scene in , very little was known about the mysterious cryptocurrency, and its value, if it had any at all, was negligible. Eventually, black market buyers and sellers saw in bitcoin a way to anonymize money transfers, especially across borders. Silk Road, an illegal marketplace on the deep web, began to use bitcoin to facilitate transactions. Fast-forward a few short years and millions have downloaded cryptocurrency investment software and are investing in digital money the same way they might invest in stocks and bonds. Hundreds of new cryptocurrency alternatives have sprung up to compete with bitcoin.
Blockchain as a Megatrend
Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. Blockchain is a type of DLT in which transactions are recorded with an immutable cryptographic signature called a hash. This means if one block in one chain was changed, it would be immediately apparent it had been tampered with. If hackers wanted to corrupt a blockchain system, they would have to change every block in the chain, across all of the distributed versions of the chain.
Trust, efficiency and security: the main advantages of Blockchain technology
